The Harmony Optical One Toslink cable is capable of eliminating distortions caused by imperfections in inductance, capacitance and resistance that are typical of coaxial cables. Toslink cables can also eliminate EMI and RFI interference. HT's fiber-glass optical cable is designed to provide outstanding low-loss, low-jitter performance while overcoming the usual limitations of cheaper fiber-optic cables. In addition, they have improved the cable's durability and implemented connectors that ensure a tight connection every time.
